Description

• Because our 404 errors are triggering rollbar errors (see #727), the following errors are included on rollbar:

2024-04-16 01:09:48 am MDT to 2024-04-16 01:10:33 am MDT (45 secs) 101 occurrences of No route matches [GET] "/locale/en-CA"

2024-04-15 08:14:32 pm MDT to 2024-04-15 08:15:12 pm MDT (40 secs) 101 occurrences of No route matches [GET] "/locale/fr-CA"

2024-04-15 05:52:56 am MDT to 2024-04-15 05:53:40 am MDT (44 secs) 101 occurrences of No route matches [GET] "/locale/fr-CA"

It would probably also be worth investigating if any of bursts of GET requests are being sent to working routes as well.
